Well, a press secretary is a big figure in an informational autocracy so the militia commander makes a favor to press-secretary to prove his loyalty to Lukashenka. She in turn has some fun and also proves her loyalty to him.
You're stretching the argument. Even if Cyber-Partisans COULD hide their identites as a nation state actor doesn't mean that the ARE doing so. As for right now the group is exactly a-political and works to overturn Lukashenka's regime with any actors who also aims for this goal.
The whole thing is an aftermath of political crysis started after completely falsified election. They are working to strike terror(also they're definitely having fun doing so) into residents of a certain neighbourhood that's especially active protesting against Lukashenka's regime by detaining and repressing whoever expresses any opinion against such practices.

As another commenter writes below they are agreeing to be in contact directly and the commander of militia basically recites his mobile number.

But it's also nastiest one cause woman is using a phrase "We don't need stripes, we need heads". For extra context protesters were marking fences in their districts with stripes with national symbols on them. So the phrase means that we don't care about the symbols, it's just a way to lure protesters out of their homes. Also she's literaly using word hunting and jokes that protesters are in red list like animals. Such attitude shows her cruel and inhuman personality in its best.
Essentially they are planning safari on protesters. Plan is something like following: women will be a bait who will lure protesters out of their homes by vandalizing symbols of Belarusian protest and militia will cover the bait by violently detaining those who will come out to protect the symbols.
Woman is Lukashenka's press-secretary and man is a commander of Belarusian Militia Special Purpose Squad(that's responsible for the most horrible acts of violence in Belarus since 9th Aug 2020 presidential election day).
